I'm not sure about Nina, but Ian is definitely a DE shipper.

Both are a DE shipper! Nina sad once on twitter "go team Damon" <3

Nina said also that he is her favorite vampire!!!!!TEAM DELENIAN FTW!

HAHA IT'S OBVIOUS!!, BOTH ARE TEAM DELENA, EVEN IF A CERTAIN MISS DOBREV REFUSES TO ADMIT IT!! SHE MAKES IT OBVIOUS IN THE COMMENTS ABOUT THE RELATIONSHIP!!

It obvious Ian is a DE fan,how could he not? He gets to have scenes with his girlfriend and kiss her as a job...i wouldnt be complaining either. And you can tell he really understands their dyamic and is geniunely interested in whefe it goes. With Nina its a little less obvious,she has aways appeared to be SE but you can also tell she enjoys doing scenes with Ian,he's her boyfriend! And I think she does ship them. However, I think she is Team Defan in general:L

Ian is 100% Delena, now whenever Nina is asked she gives more info on Stelena and avoids Delena questions...

But Nina said that she wich happy birthday to her favourite vampire Ian Somerhalder.

I hope so. Ian is 1000000% DE.

Ian said on twitter about the kissing scene: I waited for this scene so long and NBina retweeted him with: I know me too :)
or something ;)
